New Spoiler
I have a Stingray without a spoiler. I finally found a style I like, as I didn't like the GM choices when I bought the car. What about upsetting the aerodynamics of the car by adding a spoiler? Isn't the car tuned for how it is sold. In other words, should I get something adjusted after adding a spoiler? It seems that with more down-force on the rear it could be an issue. Thanks.

Most aftermarket spoilers are NOT made to produce a ton of downforce, in part because they're usually just mounted to the body panels. A real spoiler making 200 lbs of downforce should be connected to the chassis somehow.
In theory you could be upsetting the balance of the car at speed, but it really depends on how much downforce the new spoiler makes. Even so, it's not going to be much difference than a tank of fuel, I'd reckon.
Take it easy your first few times at speed on the highway just to make sure the dynamics have not changed.

Unless you're consistently in the 125MPH + club, you don't have much to worry about (unless you're buying some god-awful 4' scaffolding). I did add a wickerbill to my Camaro I track, noticed a tiny bit more of a planted feel on the track at speed, but I highly doubt you'll notice any difference by simply adding a spoiler at legal speeds. If you start doing wheelies, please come back and let us know.
ALSO, be very careful with materials used in aftermarket parts. Some ebay specials look awesome, but you waste money on prep and paint only to find out the cheap materials they're made of warp and wave like hell after a few short months

Thanks to all for the replies. I guess my instincts are correct. It will have an effect on the aerodynamics. I've only gone over a 120 a few times, so it will probably be a nonissue.
